Whole-body 18F-FDG PET/CT scan in a patient with Liver Cancer taken from the PETWB-REP dataset. The following English report (translated from original Chinese) is taken verbatim from the public dataset and has not been modified or otherwise checked for accuracy (see the end for citation).

Findings

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body scan showed: The brain morphology and structure were normal, with punctate and small patchy low-density lesions in the right basal ganglia region; FDG uptake was not significantly abnormal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
No thickening was observed in the paranasal sinus mucosa, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; FDG uptake was normal; the pharyngeal recesses were symmetrical bilaterally; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and FDG uptake was normal.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
A small solid nodule, approximately 0.4 cm in long diameter, with clear borders, was seen in the lateral basal segment of the left lower lobe, and FDG metabolism was normal; a few linear and patchy shadows were seen in the remaining lungs, and FDG uptake was normal in all of them.
No pleural thickening was seen bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
No esophageal dilation was seen, and no significant thickening or mass was seen in the esophageal wall; FDG uptake was not increased.
Both breasts were normal, and FDG metabolism was normal.
The liver has an irregular outline.
A low-density mass measuring approximately 8.0 4.8 cm is seen in the right lobe, with increased FDG metabolism (SUVmax = 11.9).
The main portal vein is not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and no obvious abnormal FDG uptake is observed.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and no obvious abnormal FDG uptake is observed.
Bilateral adrenal gland imaging shows no obvious abnormalities.
Stomach distension is poor, with slight thickening of the gastric body and antrum walls.
FDG uptake is slightly increased, SUVmax=2.6.
Intestinal distension is unsatisfactory, with increased FDG metabolism in some intestinal segments, SUVmax=5.3.
Uterus shape is normal, with no abnormal FDG metabolism observed.
No abnormal FDG metabolism observed in the bilateral adnexa.
Bladder distension is normal, with no obvious positive stones observed.
Several lymph nodes are observed in the porta hepatis, peripancreatic region, and para-aortic region, with short diameters of approximately 0.2-0.6 cm.
FDG metabolism is increased, SUVmax=2.3.
No obvious fluid accumulation is observed in the abdomen or pelvis.
Spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies and L4/5 and L5/S1 intervertebral disc bulging.
Systemic bone marrow FDG metabolism is normal.
Increased FDG metabolism around the right shoulder joint, SUVmax = 3.2.

Impression

  1. A mass in the right lobe of the liver with increased FDG metabolism is suggestive of malignancy, possibly hepatocellular carcinoma. Reactive hyperplasia of the abdominal and retroperitoneal lymph nodes is highly likely; follow-up is recommended to rule out mixed metastases.

  2. Slight thickening of the walls of part of the gastric body and antrum, with mildly increased FDG uptake, suggests possible chronic gastritis; follow-up with gastroscopy is recommended.

  3. Chronic inflammatory micronodules (solid) in the lateral basal segment of the left lower lobe. A few chronic inflammations and old lesions in both lungs.

  4. Increased FDG metabolism in part of the intestinal tract, considered physiological uptake.

  5. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges. Right-sided frozen shoulder.

  6. Ischemic lesions in the right basal ganglia region.

This case is from PETWB-REP, a curated dataset of whole-body 18F-FDG PET/CT scans and corresponding radiology reports from 490 patients with a broad spectrum of malignancies. The data were retrospectively collected from patients who underwent clinically indicated whole-body 18F-FDG PET/CT scans at the Shanghai Universal Medical Imaging Diagnostic Center between 2021 and 2024.
